Wal-Mart has once again expanded its $4 prescription drug progam, making good on its promise to spread the program nationwide. In addition to adding 11 more states to the list, it has also added 17 more prescriptions to the list. That brings the totals to 331 commonly prescribed generic prescriptions drugs available for $4 in 38 states.

If you live in Idaho, Kentucky, Maine, Massachusetts, Nebraska, Oklahoma, Rhode Island, South Carolina, Utah, West Virginia, or Washington, you can now take advantage of the $4 pricing at Wal-Mart stores.
